As shown, three pa ol' these parallel hars are secured to euch side of the traine, und the hars that are transversely opposite. tu each ot her are ut the sinne altitude, ulnl that extend ut right angles to each other are oliset in lilies-nato order.

What I claim 1s l. In amixing device of the kind described, the combination with a frame inade u of cor- Aner posts and transversely opposite tie ars arranged in pairs, of parallel defiecting rods arranged in vertically spaced series with theirends extended through the alined inner tie bars and held against endwise movements by the coperating outer tie bars, substantially as descrlbed.

2. The combination with a fra-lne made up of angular corner posts and tiebars arranged. in pairs and detachably clamped to the flanges of said corner posts, and the parallel series of deflecting rods arranged in vertically sppeed rows with their inner ends extended t ough perforations 1n the ooperating inner tie bars and held against endwise movements by the cooperating outer tie bars, substantially as described.- l

3. The combination with a frame made up of corner posts and tie bars, ofparallel de? fleeting rods arranged in vertically spaced series, and a hopper supported by the upper ends of said corner posts androvided with depending ears through whic one fof the deiiecting rods of the up er scrics is passed, substantially as described.

4. In a dei tachabl connected corner posts and tie'bars, of ara lel deilecting rods arranged in vertical y spaced yseries and detachably held in Working positions by said Atie bars, and a hopper supported by said corner posts and dctachably held in Working position by one of said deflecting rods, substantially as described.
